Quantitating the dynamics of NBD hexanoic acid in homogeneous solution and in solutions containing unilamellar vesicles

Article Abstract:

The optical properties of the chromophore NBDHA (6-(N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino)hexanoic acid) are reported. The experimental data for NBDHA in selected solvents of varying viscosity demonstrate that one- and two-photon excitation probe different components of the rotational diffusion constant and that this chromophore reorients as a prolate rotor with an aspect ratio of ~2.

Investigating internal structure differences between micelles and unilamellar vesicles of decanoic acid/sodium decanoate

Article Abstract:

The dynamics of a chromophore sequestered within the nonplanar regions of micelles and unilamellar vesicles comprised of decanoic acid/sodium decanoate are reported. The results have shown that these structures do produce different local environments, with the unilamellar vesicle being of slightly lower effective viscosity than the micelle.

Probing intermolecular communication with surface-attached pyrene

Article Abstract:

The covalent attachment of pyrene derivatives to solid substrates and their spectroscopic and electrochemical characterization is discussed. Significant intermolecular communication between adsorbate species was observed.
